About this data
This follows MISO's public real-time data feed for system load. It combines five-minute actual load, hourly cleared load and the medium-term hourly forecast, each as its own series. The values are system-wide, so they should not be treated as local resource zone loads. It is the live window on MISO demand against its forecast.
